User avatar Hello,

Non contrast helical CT Scan is the most sensitive up to 100%and specific radiologic test up to 96& (means better definitive diagnosis).

It can give also idea about the presence of obstruction and nongenitourinary conditions.

US has sensitivity of 19% and specificity of 97%. It is a good test, easy, economic and accessible in many centers.

Hope this information is useful.
Best regards.
